Circumference of a circle is always ______.

Options

  • more than three times of its diameter

  • three times of its diameter

  • less than three times of its diameter

  • three times of its radius

Solution

Circumference of a circle is always more than three times of its diameter.

Explanation:

We know that,

Circumference of a circle = 2πr

∴ Circumference = 2 × 3.14 × r  ......[∵ π = 3.14]

⇒ Circumference = 3.14 × d  ......[∵ d = 2r]

So, circumference of circle is always more than three times of its diameter.

  Is there an error in this question or solution?
